automatic gain control
(Electronics) control of a radio receiver in which the gain varies inversely with the magnitude of the input, thus maintaining the output at an approximately constant level. Abbreviation: AGC

This approach raises some concerns, such as the narrow gain control range and limitation of dynamic range of whole AGC circuit
The same basic AGC circuit
may be used, but this time the transmitted power may need to be dynamically adjusted.
To prevent the circuit from unintended operation in noisy environments, a valid preamble signal with a minimum of 192 periods is necessary to activate the AGC circuit
The device includes a one-step AGC circuit
that drops the LNA gain by 35 dB when the RF input signal is greater than -57 dBm.
